Polyvinyl alcohol PVA is a widely used water-soluble high molecular polymer. Due to its performance between plastic and rubber, it has unique strong adhesion, film flexibility, smoothness, oil resistance, solvent resistance, protective colloid, gas barrier, abrasion resistance and special treatment. Water-resistant, non-toxic and harmless, in addition to fiber raw materials, it is also used in the production of coatings, adhesives, paper processing agents, emulsifiers, dispersants, films and other products, the application of textiles, food, Pharmaceutical, construction, wood processing, paper, printing, agriculture, steel, polymer chemical and other industries.
Application in the chemical fiber industry:
Polyethylene fiber is also known as vinylon in the chemical fiber industry. Vinylon fiber is a valuable functionally differentiated fiber. Water-soluble polyvinylon fiber has two types of filament and staple fiber. Water-soluble vinylon filament is an ideal water-soluble fiber. It is a special variety of vinylon. It can be used at various temperatures from 0 to 100 °C. It has ideal water-soluble temperature and strong elongation, good acid resistance, alkali resistance and dry heat resistance. It is odorless and non-toxic after being dissolved in water. The aqueous solution is colorless and transparent, and can be naturally biodegraded in a short time.
Application in the construction industry:
High-strength PVA fiber has been widely used in building materials and has been used for the reinforcement of concrete in buildings, such as cement slabs, sewers, frontal floors, parking lots, etc. It can also be used as an ideal alternative for cement and fiberglass. PVA has also become more and more widely used in interior wall coatings and adhesives.
